SPECIFICATION forming part of Letters Patent No. 591,021, dated October 5, 1897.

Application filed September 25,1891. Serial No. 406,819. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES STAHLBERG, a resident of New York city, county, and State, have invented certain new and useful Improvements in Time-Stamps, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings and to the letters and figures of reference marked thereon.

This invention relates to and has for its objcct to provide an improved stamp in which the printing mechanism and motor therefor shall be contained in a single frame adapted to be inclosed in a relatively small casing.

The device is primarily intended to automatically present at the printing-point. the indices for registering a proper month, day, hour, and minute, although certain features of the mechanism are well adapted for use in connection with calendar devices in which the month, day, hour, &c., are adapted tobe presented to view, as will be readily understood by those skilled in this art.

The invention consists in certain novel details of construction and combination and arrangement of parts, as will be hereinafter described, and pointed out particularly in the appended claims.

Referring to the accompanying drawings, Figure l is a front elevation of a time-stamp and easing constructed in accordance with my present invention. Fig. 2 is a side elevation of the same.

Fig. 25 is a projection of the date, hour, and minute wheels, showing the arrangement of the series of numerals thereon.

Similar letters and figures of reference in the several figures indicate the same parts.

Difficulty has heretofore been experienced in this class of devices when it has been attempted to combine the type-wheel-operating mechanism and a spring-weight or other motor in the same case, due, primarily, to the extreme variation in the load carried by the spring, owing to the irregular action of the type-wheels, this being particularly the case in connection with the minute and hour wheels, which of necessity move quite frequently and must therefore be connected with a rapidly-moving, and consequently less powerful portion of the train, and it is with the object of overcoming this diiiiculty, as well as to provide a more compact and easilyoperated'device,thatI have designed my p resent invention.

In the following description I will first describe and point out the motor, or what I shallherein term the clock-train, which is somewhat peculiarly arranged, although not constituting an essential part of the invention so far as the successful operation of the type-wheel is concerned.

Referring now particularly to Figs. 3, 4:, 5, and 6, it will be seen that two mainsprings or drums A are employed, located at the lower corners of the frame, which springs carry gear-drums '1, both of which mesh with a gear-wheel 2, Fig. 5, mounted on a shaft 2, which communicates its motion to a gearwheel 3, meshing with a pinion 4 on a shaft 4;, and communicates its motion to a gear5, meshing with a pinion 6 on a shaft 6, which communicates the motion to a gear-wheel 7, meshing with a pinion 8 on a shaft 8, carrying a gear-wheel f), meshing with a pinion l0 on a shaft 10, which extends away through i the frame to the rear side, as shown in Fig. 3, and carries a pair of gear-wheels ll 11, Fig. 21, the former of which meshes with a pinion 12, mounted on a shaft 122, and carrying a gear-wheel l3, meshing with a pinion on the escapemeut-wheel shaft 14:. (Shown in dotted lines, Fig. Immediately below this shaft 1t is located a bearing for the pallot 15, the extended end of which cooperates with a pin 10, carried by the usual balancewheel and hail-spring arrangement 17. By thus locating the lieariugs for the escapement and pallet shocks or vibrations imparted to the frame in a vertical direction, such as are caused by stamping upon the ty'peavheels, do not tend to vary the speed of the clock-train, as will be hereinafter more particuhtrlymentioned.

Returning now to Figs. and 5, it will be seen that the type-wheels are located, preferably, at about the center of the frame, near the top, on a single shaft B, iirposilion to bring any of their indices in line at the top, and the first three wheels and the hour and minute units and tens wheels are adapted to be driven from the clock-train by three systems of gearing, which may form branches from the clock-trai u,in each of which branches is interposed what I shall herein term an equalizing-spring that is to say, a spring which permits of the intermitting action of the type-wheels while the clock-train moves regularly and at the same time prevents any variation of the load on the clock-train by reason of such intermitting action of the type-wheels.

The branch for driving the minute unitswheel, which is allowed to move once a minute by an escapement to be presently described, is as follows: Referring to Figs. 5 and 6, 2 indicates a gear-wheel on the minuteunits-wheel and l indicates a gear-wheel meshing therewith journaled loosely on the shaft 8, but connected therewith through the medium of a small coil-spring 8. Thus when the shaft 8 is rotated by the clock-train before mentioned, it, through the medium of the spring 8, tends to rotate the minute units-wheel; but if said wheel is restrained then the power to move the same is stored in the spring 8, and in order to cause the proper movement of the minut'esavheel, as before mentioned, a small pinion 3, journaled in the frame, meshes with the wheel 1 and is mounted rigidly on a shaft 4, passing through to the back of the frame and carrying a stopwheel 5, provided with a series of stop-points which strike against a stop [5 in the form of a shaft, which shaft has a small notch or cutout portion thereon through which the points can pass when the shaft is properly rotated. This shaft is driven from the clock-train by means of a pinion 7, which meshes with the wheel 11, before mentioned.

The pair of wheels 11 and 11, before nienl tioncd, while they are mounted on the same shaft are yet capable of an independent rotation, whichenables the wheel ll to be turned and theininutc units-wheelcontrolled thereby properly set. To accomplish this, the wheel 11, Fig. 21, is loosely journalcd on the shaft: 10, before mentioned, and is pressed against inclined face projections 9, Fig. 22, on said wheel 11 by means of the spring n, as shown in Fig. 21, which projection cooperates with suitable depressions or openings in the firstmentioned wheel and forms a clutch connection, thus under normal circumstances causing the same to move in unison; but when the wheel 10, which meshes with the wheel 11, is turned by means of the knurl 11, Figs. 3 and i, the type units-wheel will be turned in unison, while the running of the Cl()t'l(- train will not be interfered with unless it be a slight acceleration of the escapement end of the train during the ti me the said operat ion is taking place. The gear 11, it will be seen, is directly in the type-wheel train.

The mechanism for driving the minute tens-wheel consists of a gear-wheel 2 mounted on said minute tens-wheel and moshing with a small gear 1 journaled loosely on the shaft 4, but connected therewith through a coil-spring at, similar to the one heretofore described.

The hour-wheel branch from the motor or clock-train commences with a gear-wheel 1, Fig. 5, mounted on the shaft 2", deriving its motion therefrom and meshing with a wheel 2 on a shaft 5, carrying a wheel :5, ion rnaled thereon through the medium of a collar 20', Fig. 24, and connected to said wheel through the medium of a spring L and drum 21., similar to the spring 8. The wheel 23 meshes with a gear-wheel o carried by the hour wheel.

In Fig. 11 the year-wheel is indicated by the letter 13, the minute units-wheel 15' minute tens-wheel l3, hourwheel 15, date units- Wheel B",date tens-wheel l3",and month-wheel B and also in this figure are shown the gearwheels on the type wheels heretofore re' ferred to.

As in the ease of the minute units-wheel before referred to, with the trains of gearing thus described, so the minute tens-wheel and hour-wheel would, if left to themselves, rotate continuously and at no specified moment could they be relied upon to present indices at the proper printing-point, and in order to restrain them, while permitting power from the clock-train to be stored in their respee tive equalizingsprings, 1 preferably employ locking wheels and levers quite similar to those described in my prior application, Serial No. 381,888, tiled February lb, 1801., and consisting (see Figs. 6 and 7) particularly of locking-wheels Z) respectively, having square notches between the teeth, into which fit correspondingly-shaped ends of the lOUling-levers 1) which are held in engagement by the springs b, but are adapted to be re- ITO leased by cams or projections on the preceding wheel-that is to say, the locking-lever b" for the minute tens-wheel is adapted to be released by the minute units-wheel and the locking-lever for the hour-wheel is adapted to be released by the minute tens-wheel. This is accomplishedby locating cams b on the minute units-wheel in posit ion to lift the lock ing-lever Z)" by cooperation with the pins 1) thereon at the moment when the minute unitswheel is passing from 9 to 0. In the illustration shown two sets of digits are shown on the minute units-wheel, and consequently two cams b dotted lines, Figs. 7 and 15, are necessary in order that the proper registration of the minutes may take place. On the minute tens-wheel, Fig. 14, are located similar cams b, which engage similar pins on the locking-lever for the hour-wheel and release the same at the moment when the minute tens-wheel is passing from 5 to 0. it being necessary in the case of the minute tens-wheel to employ numerals running only from O to 5, as there are only indicated fifty odd minutes. On this wheel I have shown three sets of numerals, and it must therefore cation, I have termed operating-segments,

and mutilated gears for rewinding the same. The operating-segments are plates or segments lettered in the present drawings E, which are journaled on the hubs of each of the three type-wheels last mentioned, being held thereon by collars c, Fig. 11, which permit of free and independent rotation. The same collars hold the locking-wheels E'in place, but the latter are connected rigidly with the wheels, being for this purpose preferably located inside or between the segments and wheels within the recess, as shown in Figs. 11 and 16. Each of the segments E, while they are free to rotate independently in one direction, is caused to lock with the type-wheel when moving in the opposite direction and rotate said type-wheel. This looking, or, more properly, ratchet, mechanism consists ofa pivoted pawl f, which passes through an aperture 6 in the segment and engages the locking-wheel, as shown in Figs. 12 and 16, the pawl being held in engagement by the springf, Fig. 12, secured to the segment.

Besides the segment the date units-wheel carries a gear-wheel G, Fig. 8, which meshes with a gear-wheel G on the shaft 9, which shaft carries a corresponding pinion g, Fig. 9, meshing with the gear G with which the mutilated gears 9 Fig. 9, 9 Fig. 10, respectively, for the month and date tens-Wheel are rigidly connected. Said mutilated gears are for rewinding the segments for these last-mentioned wheels. They are, through the connections just described, turned in unison with the date units-wheel, and to cause the proper rewinding of the segment for the date unitswheel a connection with the clock-train is made as follows: On the shaft 2, with which the mainspring-drums are connected, I provide at an internal point the pinion H, adjusta'bly mounted thereon and meshing with a gear-wheel II, Fig. 8, which is mounted on the hub of the mutilated gear h for rewinding the segment of the date units-wheel. It will be understood, of course, that the relative proportion of the gears and the location of the teeth on the mutilated gears is suchas that they are out of the way of the teeth on the segments at all times when said segments are to be moved, which being a matter for calculation is easily determined by those skilled in the art, as indicated in my beforementioned application.

Each of the segmentsha a section of gearteeth I at one side thereof, which mesh with pinions I, connected by flexible connections '5 with operating-sprin s 1*, Figs. 8, 9, 10, and 5, which are put under tension when the segments are moved bythe mutilated gears, and in order to prevent said segments escaping from said pinions I or making too great a movement,which might occur under some circumstances, the section of gearing] terminates in a wide tooth I or projection, which cannot pass the pinions, and hence when this portion reaches said pinion the segment is of necessity arrested in this fore ward movemen t.

Thus far in connection with the month and date wheels I have provided mechanism only for causing their forward movement which, if unrestrained, would prevent any proper registration or cooperation of the parts. To accomplish a proper registration ,they are held in check against the tension of the operating springs I by means of locking-levers K K K for the date units, date tens, and month wheels, respectively, Figs. 8, 9, and 10, which locking-levers are similar to those heretofore described and engage the locking-wheels E in similar manner. The locking-lever K for the date units-wheel is adapted to be released once in twenty-four hours by means of the hour-wheel, which latter, therefore, is provided with one cam 7tand with a series of indices representing the hours for the complete daya. m. and p. m. The single cam is under ordinary circumstances cooperates with the pin loon the lockingdever K and releases the same to turn the units-wheel forward one space once in twenty-four hours,

and the units-wheel is caused to release the tens-wheel not directly, as in the former instance, but through the medium of the mutilated gear for rewinding the segment of the tens-wheel, which mutilated gear, as before mentioned, moves in unison with the unitswheel. Thisgearcarries,preferably,onadisk secured on one side thereof pairs of projections or cams], Fig. 20, which pass beneath and elevate a releasing-lever L, connected rigidly with the locking-lever K. Thus when said cams or projections are brought to the proper point they release said locking-lever and permit the tens-wheel to advance. The illOlitlbWliGOl loclcing lever is operated in a similar manner by means of a single projection Z on the mutilated gearg, Fig. 10, which passes beneath a lever L on the lockinglcver K As accessory to the shipping mechanism for the long and short months to be now described the date units-wheel is provided with two sets of digits and two extra figures 1. Thus the indices read 0', l, 1, 2, 23, the, to 9, when the same order is repeated, and the date tens-wheel is provided with three sets of numerals, coi'lsisting of two figures 1, two .ligures 2, and a single figure 3, with a space equal to the single figure between each set of .iigures. 'lh us on this wheel the appearance is lirst a space or blank, then two figures 1, "followed by two figures 2, a single figure 3, another blank, &:c., Fig 25.

Besides being released by the cam on the hour-wheel the locking-lever K is adapted to be released at certains intervals to compensate for the shipping of the dates at the end of short months and also to skip the extra one on the date units-wheel at the tenth and twentieth day, which is accon'lplishcd by mounting on the side of the mutilated gear g opposite to the cam l, three series of projections adapted to cooperate with the skipping-lever M, which engages a pin M on the locking-lever K for the date units-wheel, Figs. 8 and 5). One of these projections m, which is adapted to compensate for the shipping of days at the ends of the months, is in the form of three steps, Fig. 23, any one of which is engaged by the lever M, according to the longitudinal position of the shaft carrying said lever, as will be presently explained, and the remaining two project-ions m cause the proper shipping at the tenth and twentieth days. The operation of this particular mechanism as follows: Assuming that the date unitswheel is indicating the li rst part of the month, from the first to the ninth day, at the moment it moves from 0 to U the first of the pairs of projections Z, Figs. 0 and 20, cooperates with the lever L and permits the tenswheel to advance from the blank space to 1, causing the next impression to be for the tenth day. As the units-wheel continues to rotate the second figure 1 thereon is brought to the printing-point by reason of the el'lgagement of one of the projections m with the sl ipping-lever M, causing the locklug-lever K to be disengaged during the passage of a second tooth, the pin it" engaging the cam 71 on the hour-wheel, causing the release for the passage of the first tooth, the result being, as just stated, the second figure 1 is brought to the printing-point and with the first figure 1" on the tens-wheel makes the impression for the eleventh day. The second of the pair of projections l now comes into action as the units-wheel moves from the second figure 1 to the figure *2 and causes the tens-wheel to have another move mentnamely, from the first to the second figure 1. Thus the next imprint will be proper for the twelfth day. The units-wheel then continues its regular motion until the end of the nineteenth day, when as it moves from the 11 to 0 the first figure 2 on the tens-wheel will be advanced to the printing position by reason of the engagement of the first one oi. the next pair of projections or cams Z causing imprint of the twentieth day to be made. The units-wheel then advances two spaces, skipping the first and bringing the second figure l into the printing position, indicating the twenty-first day, the action being the same as described with relation to the twelfth day namely, one of the pins on passes beneath the lever M, elevates the locking-lever K, and brings the second figure 1 to the printing-point on the Ul1ltS\Vl](-\Olt11tl as the units-wheel moves from 1 to 2 the second one of the pair of projections Z causes the tens-wheel to ad Vance, bringing the second figure 2" into position to indicate the twenty-secoinl day. This order is then maintained until the end of the month is reached, when a variable shipping has to be made and in which use is made of the projection I)l., having three steps thereon, as before described, as follows:

The lever M is mounted on the shaft M", which is longitudinally movable in its bearings and provided with a spring M, Fig. 18, to hold the lever in position and the hnurl fil for drawing it in the opposite direction, with an irregular cam M for holding the shaft and lever in proper longitudinal position accord ing to the number of days to be skipped. Thus when the month has but twenty-eight days the shaft is moved to throw the pin M on the highest cam, which throws the lever M into position for ei'igaging the first step on the projection in. This occurs as the unitswheel is passing from 8 to 9" and causes the locking-lever K to be held out of engagement until the second figure 1 is brought to the printing-point, the tenswheel in the meanwhile having made two ships by reason of the passage of both of the projections Z beneath the lever L. 'lherelore it presents a blank, and the next indication will be for the first day of the month. Should the month I have thirty-one days, the lever M and its advanced under all circumstances as the date tens-wheel moves from figure 3 to blank,

IIO

but as the in utilatcd gear for rewindiug tho month-wheel segment upon which the projection Z for releasing the month-witeel-locking lever is located makes but one revolution in a month by reason of the gearing G, g, g, and G before explained, the release of the locking-lever K is easily regulated. With this arrangement it is necessary only to set the pointer m Fig. 4, at any time during the month to point to the space indicated on the dial as proper for the number of days contained in that month. Thusif a month have twenty-nine days the pointer is turned t the number 29 on the dial, which places the pin M on the second highest cam, and for months containing the other numbers of days it is correspondingly adjusted, always causing the skipping-lever to move to the proper position for skipping the requisite number of days.

By arranging the gearing, skipping, and releasing mechanism for the month and date wheels as thus described I am enabled to employ but few and inexpensive parts, the printing-wheels are brought close together, making a proper indication, and the accuracy of the operation is insured, besides which a most important result may be accomplishednamely, that of the setting of the date-wheels without the necessity of going through the extremely tedious operation of setting the stamp by turning the minute-wheel or by taking the mechanism apart. This result, which I is of very great importance, is accomplished by mounting the mutilated gears g g and the attached gear-wheel G rigidly on a shaft 0, which extends out in rear of the frame and is provided with a knurl O for turningsaid mutilated gear and through the gear G pinion 9, and gear G turning the date unitswheel, the locking-wheel for the latter of course having been released preferably by means of the handle 0, attached to the shaft 0, on which the locking-lever K is rigidly mounted, said handle 0 being in convenient position for operation simultaneously with the turning of the knurl 0'.

With this setting mechanism for the date and month wheels, in connection with the setting mechanism before described for the minute and hour wheels, the stamp may be quickly and accurately set, a convenience which will be at once appreciated by those handling this class of stamps as heretofore constructed.

If reference be made to Fig. :3, the proper relative relation of the stepped projection m, cams or projections Z, and projections Z will be seen, and it will be noted that the last projection Z of the pair and the projection Z operate at nearly the same moment with the last step on the cam m.

The main operating-springs are manually wound by a key applied to the stems A in the usual manner, and to the back end of the shaft 2 a suitable hour-hand for indicating the hour on a dial P at the front of the clock is provided, and on the shaft l" is secured a gear-wheel 7), which meshes with a pinion mounted on a sleeve 17', carrying a minutehand for indicating the minutes on said dial, the sleeve itself beingjournaled on a projecting end of shaft 2, as shown clearly in Fig. 3.

The year-wheel is adapted to be moved by hand at the end of the year, and for the purpose of holding it in place it is provided with a series of depressions or openings Q, into which a spring retaininglinger Q ii ts, as will be readily understood, this feature being common to stamps heretofore constructed.

The casing in which the mechanism is mounted is preferably rectangular and provided with means for securely closing against meddlesome persons, the only parts exposed being the peripheries of the type-wheels at the printing-point, and as these are locked against movement in both directions practically there is little or no danger of the stamp being intentionally altered as to the date indicated.

The platen or pad R for driving the paper or material upon which theimpression is made against the type-wheel is mounted on an overhanging arm R, which is securely fastened to the door 13*, forming the rear side'of the machine, and is journaled on vertical pivots, as shown in Fig. 2, which construction, besides forming a very neat and easily-constructed one, absolutely prevents injury to the stamp by striking the type-wheel with the platen during the time the door is open and the type-wheels are being set, as when said door is open the platen is of necessity thrown off to one side.

The stamp as a whole has been found exceedingly efficient in practice, and by reason of the particular manner of equalizing the load on the mainspring of the motor practically no variation in the clock-train is caused by the irregular movement of the type-wheel, and, further, by arranging the bearings for the escapement-wheel and pallet in a vertical plane, orin a plane parallel with the direction of the impact or shock given in making an impression, little or no inconvenience results when an impression is made at the moment the pallet is in engagement with the escape merit-wheel.
